Commissioning
4.4 Setting up a STEP 7 project
Connecting the SIMODRIVE 611U to the Technology CPU
48 Product Information, 03/2008, A5E00272066-05
Homing mode "Homing output cam and encoder zero mark"
Operational sequence
The axis traverses in the specified homing direction. Once the homing cam signal is
reached, the velocity of the axis switches from the homing approach velocity to the homing
reduced velocity. Once the homing cam is left, the axis is homed at the next detected zero
mark of the encoder.
Hardware configuration
The homing cam is connected to a free SIMATIC peripheral input (either on the integrated
input of the technology CPU or on the remote input on the DP(DRIVE)).
